Related to cytoplasmic inheritance: Maternal inheritance
transmission of characters dependent on self-perpetuating elements not nuclear in origin (for example, mitochondrial DNA).
Synonym(s): extranuclear inheritance
the acquisition of traits or conditions controlled by self-replicating substances within the cytoplasm, such as mitochondria or chloroplasts, rather than by genes on the chromosomes in the nucleus. The phenomenon occurs in plants and some animals but has not been demonstrated in humans.
cy·to·plas·mic in·her·i·tance(sī'tō-plaz'mik in-her'i-tăns)
Transmission of characters dependent on self-perpetuating elements not nuclear in origin (e.g., mitochondrial DNA).
cytoplasmic inheritanceThe genetic effects of DNA situated in MITOCHONDRIA.
extranuclear inheritancethe control of certain characters by genetic factors located in the cytoplasm of EUKARYOTES. These cytoplasmic mechanisms can show themselves as general ‘maternal’ influences (since the female gamete contains more cytoplasm than the male) as in the control of shell coiling in the snail Limnaea. DNA has also been located in several cytoplasmic organelles, such as a MITOCHONDRION or a CHLOROPLAST, which can replicate and function independently of the nucleus.
pertaining to or included in cytoplasm.
include secretory inclusions (enzymes, acids, proteins, mucosubstances), nutritive inclusions (glycogen, lipids), pigment granules (melanin, lipofuscin, hemosiderin). See also inclusion body.
the cytoplasmic organelles, chloroplasts and mitochondria contain DNA which contains a number of genes. These extrachromosomal genes are transmitted to daughter cells via cytoplasm. Called also maternal inheritance.
cytoplasmic nuclear inclusion
see inclusion body.
includes microtubules, centrioles, cilia, flagellae.
